can_tdc_changelink() return -EOPNOTSUPP under this condition:

  !tdc_const || !can_fd_tdc_is_enabled(priv)

But this function is only called if the data[IFLA_CAN_TDC] parameters
are provided. At this point, can_validate_tdc() already checked that
either of the tdc auto or tdc manual control modes were provided, that
is to say, can_fd_tdc_is_enabled(priv) must be true.

Because the right hand operand of this condition is always true,
remove it.
